S2
7
capacitor connection for the DC-to-DC converter (between S1 and S2)
VUP

DC-to-DC converter output (must be decoupled with 100 nF to ground)
I/O
9
input/output to and from the card reader (C7I); see Fig.7
SGND
10 signal ground
CLK
11 clock output to the card reader (C3I)
V_CC
RST
12 supply voltage to the card reader (C1I)
13 reset output to the card reader (C2I)
V_DDS
DEL
14 signal supply voltage
15 external capacitor connection for the delay on voltage supervisor
PRES
16 card presence indication input (active LOW); note 1
SIMI/O
V_DDI
SDA
SCL
SIMERR
SAD0
SAD1
17 input/output to and from the microcontroller (internal 20 kΩ pull-up resistor connected to V_DDI)
18 supply voltage for the interface signals with the system
19 I²C-bus serial data input/output
20 I²C-bus serial clock input
21 interrupt output (active LOW; internal 100 kΩ pull-up resistor connected to V_DDI)
22 I²C-bus slave address selection input
23 I²C-bus slave address selection input
SIMCLK
24 external clock input
Note
1. Card presence input with negative current source. To be used with the card reader switch connected to V_DDS
or V_DDP. The switch is normally closed when the card is not present. If the switch connection is open-circuit or pin 16
is not connected, then the interface will always detect a present card (see Fig.7).
